Complete walkthrough from the C64 game "Impossible Mission"
Visiting the code rooms isn't necessary to complete the game but solving the audio puzzle by playing the sequence in ascending order earns extra robot snoozes or lift inits which come in handy completing difficult rooms.
>>>UPDATE: December 2009<<<
There is a newer version from that video in a better quality.
It shows some ingamemessages to explain that game for viewers who doesn`t know that game. It was played complete new and a bit faster too and the videoquality is much better.
